INDIANTOWN, Fla. — A 17-year-old boy is under arrest after Martin County deputies say he shot and killed a 14-year-old boy Sunday evening in Indiantown.

Officials said the incident happened inside a home in the 14000 block of SW 172nd Avenue around 5:30 p.m.

The 17-year-old, whom FOX 29 is not naming because of his age, is facing a charge of aggravated manslaughter of a child.

The victim has been identified by MCSO as 14-year-old Jamarion Jones. Jones was at a friend's home when he was shot.

According to an arrest report, the 17-year-old initially lied about his involvement in the shooting, claiming an "unknown and unseen gunman had shot Jimarion from the hallway outside of his bedroom."

However, detectives said the 17-year-old eventually changed his story and "admitted that he had accidentally shot Jimarion while 'dancing with' the gun."

The teen said he was messing around with the weapon and "ultimately his 'finger slipped' causing the gun to discharge a single round which struck Jimarion in the torso," according to the arrest report.

Jones was taken to Tradition Medical Center where he tragically died from his injuries.

A friend who was with the 17-year-old suspect at the home said "he and Jimarion asked [the suspect] to stop pointing the gun and waiving it around recklessly."

It's unclear where the weapon came from. That friend said he had never seen the gun before until the suspect "pulled it out of some unknown location in his room."
